From crazed gunman to lack of food labelling, David Isaacson takes us in his first week of the Rio Olympics Games. SEEDS OF SUCCESS: Lawrence and Matthew Brittain are the first South African siblings to win Olympic medals, at least since readmission. Lawrence got his silver in the men's pairs this week, and Matthew was a member of the golden four at London 2012.The good news is there are still two younger brothers, James and Charles, coming through the ranks. Said Matthew: "My dad should sell his sperm."WHAT'S IN A NAME: It's unclear if there were siblings in the pre-isolation days. Back in the mists of time, there were some medallists sharing surnames.story_article_left1There was Reggie Walker, the 100m gold medallist from 1908, and double cycling medallist James Walker from 1920. There have been a few Smiths over the years - shooter David Smith (1912), cyclist William Smith (1920), boxer Willie Smith (1924).MADIBA MAGIC: One of the tracksuits used by Team SA here features the flag with a silhouette of Madiba on the left breast, but Olympic rules prevented it from being used for the opening ceremony. "It was thought we could utilise that particular tracksuit," said chef de mission Tubby Reddy."[But] we wouldn't have been able to use it in the opening ceremony because it's got the face of Madiba on it. They don't allow images of ... symbols that they see as political."SMITHS ROW: There are a mountain of Smiths in the rowing squad. John "Bean" Smith, one of the golden rowers from four years ago, should not be confused with Jonty Smith of the heavyweight men's four.London Olympian Naydene Smith, who's dating Bean, was a member of the national squad until recently. And Carolyn Thompson, the wife of Bean's partner, James, used to be a Smith.None of them are related.WILD CARD: Hurdler Lj van Zyl found himself in an unexpected race against a car this week. He and some others were returning to the village in a taxi, and to ease their clearance through security, he had taken his accreditation card from his neck and placed it on the dashboard.Van Zyl forgot to retrieve it, remembering only as the taxi headed off. Van Zyl sprinted after it, but the driver disappeared. The hurdler managed to get another card printed, but not long afterwards he received a pleasant surprise - the driver returned the old card.block_quotes_start It wasn't a crazed gunman, but rather the door of a metal locker that had fallen off its hinges and crashed to the floor block_quotes_endJOYRIDE: Swimmers heading to the pool for competition on Friday night received the shock of their lives when their bus driver took them to the athletics stadium instead.After frantic calls from team managers to organisers, the driver got them back to the pool, apparently at high speed.WHAT WAS THAT!: The loud bang in the cycling media room this week caught our attention quickly. With reports of shots fired at an official Olympic bus carrying journalists, we had to make sure our lives weren't in danger. Fortunately, it wasn't a crazed gunman, but rather the door of a metal locker that had fallen off its hinges and crashed to the floor. Welcome to the Rio Games.FOOD FOR THOUGHT: The Games organisers have heard complaints about the lack of labelling of food in the canteen so athletes can see what they're eating...
